Dear SCO Customer, Support Level Supplement (SLS) ptf3363e, the SCO UnixWare Large Volume fdisk and sysdump Driver Supplement, resolves all of the the problems listed below. SLS ptf3363b addressed this issue: - fdisk failed with disks larger than 64GB. SLS ptf3363 allows UnixWare to work with disks greater than the 64GB limitation, and the maximum partition size handled by fdisk is now 2 terabytes. Note: This changes the size of the maximum disk that fdisk can deal with. It does not change the maximum filesystem size, which is still 2GB. SLS ptf3363c addressed this issue: - Systems running the Online Data Manager (ODM) software on configurations with encapsulated, mirrored root disks sometimes hang during a panic. SLS ptf3363d addressed this issue: - Possible data corruption occurs when running heavy disk-intensive i/o. SLS ptf3363e additionally addresses these issues: - A memory leak occurs in the 56-, 512- or 1982-byte kma pool as seen by sar(1M) and rtpm(1M). - Messages appear in the osmlog file recording failures of the fork() or exec() system calls due to a shortage of kernel memory. - The prtvtoc(1M) command fails to complete.
